Setup Hazelcast

{{< tabs "Self-Hosted" "Kubernetes">}}

{{% codetab %}} You can run Hazelcast locally using Docker:

docker run -e JAVA_OPTS="-Dhazelcast.local.publicAddress=127.0.0.1:5701" -p 5701:5701 hazelcast/hazelcast

You can then interact with the server using the 127.0.0.1:5701. {{% /codetab %}}

{{% codetab %}} The easiest way to install Hazelcast on Kubernetes is by using the Helm chart. {{% /codetab %}}

Create a Dapr component

The next step is to create a Dapr component for Hazelcast.

Create the following YAML file named hazelcast.yaml:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: pubsub.hazelcast
  version: v1
  metadata:
  - name: hazelcastServers
    value: <REPLACE-WITH-HOSTS> # Required. A comma delimited string of servers. Example: "hazelcast:3000,hazelcast2:3000"

{{% alert title="Warning" color="warning" %}} The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}). {{% /alert %}}

Apply the configuration
